Title
(EN) METHODS FOR PREPARING POLYESTER-BASED NANOCOMPOSITES
(FR) PROCEDES DE PREPARATION DE NANOCOMPOSITES A BASE DE POLYESTER
Abstract
(EN)
The invention provides methods for preparing composites of polyester and layered compounds. In one embodiment, the invention provides a method for preparing a composite of a poly(alkylene terephthalate) and a cation-modified layered compound via in-situ polycondensation in solvent. In another embodiment, composites are made with polyesters of average molecular weight of 10,000 g/mol or more by mixing the polyester and a layered compound in the presence of a solvent, such as ortho-dichlorobenzene.
(FR)
L’invention prévoit des procédés de préparation de composites de polyester et de composés lamellaires. Dans un mode de réalisation, l’invention prévoit un procédé de préparation d’un composite d’un poly(alkylène téréphtalate) et d’un composé lamellaire à modification cationique, via polymérisation in situ dans un solvant. Dans un autre mode de réalisation, des composites sont préparés à partir de polyesters de poids moléculaire moyen de 10 000 g/mol ou plus, en mélangeant le polyester avec un composé lamellaire en présence d’un solvant, par exemple l’ortho-dichlorobenzène.
